Clinton’s emails have been under scrutiny since it was revealed she used a private server in her Chappaqua, New York, home while she was the top U.S. diplomat. Government and congressional investigators have been trying to determine whether she sent or received classified information on unsecured email.

Last month, the inspector general of the U.S. intelligence community alerted the Justice Department about classified information included improperly on email that went through Clinton’s home server. The referral to the Justice Department did not seek a criminal probe and did not specifically target Clinton.

The two officials cited by the Post also said that the FBI was not targeting her.

A spokesman for Clinton’s presidential campaign tweeted Tuesday that that Post story “doesn’t change anything … IG sent ask to DOJ to confirm emails are secure.”
